Description

TECHNICAL FIELD

This disclosure relates generally to providing virtual assistance to a user, and more particularly to a system and a method of providing real-time remote assistance to a user.

BACKGROUND

Remote assistance based services are very popular nowadays, which allows a user to obtain services through online platforms. The user can obtain remote assistance as a solution or service or product on demand from any location in the world. In conventional solutions, any person can learn new technologies or implement solutions via media content available on internet. Such services may allow user to implement the solutions on their own, however it further requires the user to repeatedly ask for assistance to understand the solution completely. In such scenario, when the user needs continuous assistance till the time a task is completed, the process may become extensive and complex. The time taken to provide final solution to the user increases if the user needs repeated solutions from an expert and has to repeatedly input queries to find a solution.

There are existing solutions which provides situation-based assistance to the user by enabling the remote experts to use existing augmented reality based technologies to guide the user. Augmented-reality is very useful in providing visual assistance to the user. Such solutions are mainly one-time generated guidance, even though there are some solutions which allows experts to provide additional information to the user. Even in such cases, the user is required to provide queries continuously and learn to implement the augmented solutions. Only a skilled operator familiar with such solutions can implement the remote solutions properly. Even the simulation technology requires an operator to be skilled enough to operate in simulated environment. Such kind of remote assistance is not useful for an inexperienced or novice user.

More research is now focused on understanding user intent in a comprehensive way. At the same time, various technologies such as augmented reality, virtual-bot, customized avatar, scenario based recorded content are known in the art to facilitate the user to perform a task. In a skilled person's brain these connections are formed during training of desired skill. When the skilled person is provided with similar environment and problem statements these patterns are followed. There are no techniques which can leverage the skills from an expert and replicate the same on an unskilled user. Accordingly, capturing guidance from the skilled expert while the skilled expert is experiencing a similar environment to that of the user, to provide comprehensive assistance to the user in real-time is significantly required to improve efficiency of virtual assistance systems.

The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

In particular, the assistance system 200 includes the user interface 201 which is configured to receive a request from the user 103 for remote assistance to complete a task in real-time. Herein, the user 103 may be an unskilled person, inexperienced person, an untrained person, or a novice who requires remote assistance from a skilled expert to perform a task. The user interface 201 takes user request in terms of query which may be audio or text input. Further, the user request may include user query data 213 in terms of what kind of assistance the user 103 would require from the assistance system 200. Upon receiving user request, the assistance system may verify user credentials 214 to check whether it is a registered user or not from a query resolution database 212. In case, the user is not registered with the assistance system 200, it allows a new user to register itself and the user credentials are updated in query resolution database 212. Further, the assistance system 200 determines the kind of skills that would be required to perform the task for which user requires real-time assistance. Accordingly, the assistance system 200 requests the expert allocator module 210 to provide a list of experts based on the required skills and the availability of the expert. The assistance system 200 identifies a skilled expert from the list of experts and triggers the skilled expert for providing remote assistance to the user.

Further, the recording module 207 allows the assistance system 200 to capture the holographic information of the one or more objects associated with the task for which the user needs assistance to complete the task.

The holographic information includes holographic images of one or more physical objects captured using one or more sensors 206, including camera. The recording module 207 is communicatively coupled with the mixed reality system 102 of the skilled expert 104 via a high throughput communication network 105. The recording module 207 streams the captured holographic information of the one or more objects to the mixed reality system 102 associated with the skilled expert 104.

As will be further described in greater detail in conjunction with FIGS. 2B and 3, the assistance system 200 provides holographic information of user's environment representing one or more objects associated with the task, to the skilled expert 104 in order to generate a mixed reality environment for the skilled expert 104, and to receive one or more brain signals associated with the skilled expert 104 while interacting with the mixed reality environment to perform the task, for providing real-time remote assistance to the user 103.

FIG. 2B illustrates a block diagram of a mixed reality system associated with a skilled expert, in accordance with some embodiments of the present disclosure. The mixed reality system 300 may be configured to generate a mixed reality environment of one or more objects associated with the task to be performed by the user. The mixed reality system 300 may include at least one processor 301, and memory 302 that may store one or more instructions that, when executed by the at least one processor 301 cause the at least one processor 301 to perform various functions in order to generate virtual simulation of the one or more objects associated with the task for the skilled expert 104, in accordance with aspects of the present disclosure. The mixed reality system may include a network interface 305 to receive user query and user's environment details through the communication network 105. The mixed reality system 300 may include various modules 303 such as an adaptation module 306, a data visualization module 307, a controller interface 308, and a haptic feedback module 309, brain-computer interface 310, and the like to create virtual simulation of the user's environment for the skilled expert 104. In some embodiments, the assistance system 300 may store various data 304 in the memory 303 (for example user query data 311, holographic information 312, virtual object data 313, haptic feedback data 314, brain signals data 315, and other data 316) that may be captured, processed, and/or required for creating mixed reality environment for the skilled expert 104.

In particular, the mixed reality system 300 includes an adaptation module 306 which collects and validates the holographic information 312 associated with the one or more objects received from the assistance system 200. Upon receiving the holographic information 312 from the recording module 207, the adaptation module 306 may determine one or more assets required to create a mixed reality environment for the skilled expert. In an embodiment, the adaptation module 306 retrieves the virtual object related data 313 from a centralized server (not shown in FIG. 2B) connected with the mixed reality system to create a virtual simulation. The virtual object related data may include data related to virtual objects models and virtual scenes downloaded from the content delivery network in order to create virtual simulation based on real-world environment.

Further, the data visualization module 307 of the mixed reality system 300 maps the one or more objects associated with the task into a virtual simulation for the skilled expert through which the skilled expert can interact with the mixed reality system 300 to perform the task. The data visualization module 307 implements various motion technologies known in the state of art to generate visual representation of the one or more objects associated with the task at user's end. The controller interface 308 allows the skilled expert to perform one or more actions on the virtual representation of the one or more objects in order to assist the user 103 to complete the task.

In addition to above, the mixed reality system 300 includes the haptic feedback module 309 which responds to the movement of hands, legs or other body parts of the skilled expert. When the skilled expert is performing the one or more actions on the virtual representation of the one or more objects, the mixed reality system 300 records one or more brain signals corresponding to responses, gestures, and movements of the skilled expert. In an embodiment, the mixed reality system 300 captures touch, vibrations and motions made by the skilled expert while interacting with the virtual simulation of the one or more objects. In an embodiment, upon receiving the haptic feedback through the haptic feedback module 309, the mixed reality system 300 records one or more brain signals associated with the skilled expert through brain computer interface 310 to be shared with the unskilled user through secured communication network 105.

In addition to above, the mixed reality system 300 may encrypt the one or more brain signals recorded from the skilled expert to be transmitted across the communication network 105 to the assistance system 200. The encrypted brain signals may be encrypted using security keys provided by the assistance system 200.

Referring back to FIG. 2A, the one or more brain signals associated with the skilled expert may be received by the computer-brain interface 208 of the assistance system 200. The one or more brains signals may be decoded by the assistance system 200 to generate one or more execution commands for the user to complete the task.

In particular, the computer-brain interface 208 decrypts the encrypted form of the one or more brain signals associated with the skilled expert into plain brain signals. Further, the assistance system 200 implements extraction technique to determine meaningful information from the plain signals in order to generate one or more execution commands for the user to complete the task.

Furthermore, the data collection and analysis module 209 of the assistance system 200 extract a plurality of features associated with performing the task from the one or more brain signals decoded by the computer-brain interface 208. The one or more extraction techniques may implement existing band power, time frequency representation and the like to extract significant features for determining true intent of the brain signals. The brain signals (also referred as EEG signals) are electroencephalogram signals that records activity of brain of an individual. The plurality of features associated with brain signals represents a distinguishing property, a recognizable measurement, and a functional component obtained from a section of a pattern. The plurality of features are extracted so as to minimize the loss of important information embedded in the signal. For example, when an individual is typing in happy mood, there might be some other activities going on like eye blinking or some other muscular activity like legs shaking etc. apart from typing as main activity. In such case typing or touching on keyboard forms relevant set of features and rest are irrelevant information but the captured EEG signals will contain all of the features. In order to separate these features in given context the assistance system 200 uses feature extraction techniques. Many popular techniques known in the state of the art such as Fast Fourier Transform (FFT), Wavelet Transform (WT), Eigenvectors, Auto-regressive and the like may be used for feature extraction.

Further, the plurality of features extracted from the received brain signals are classified to clean the artifacts from the extracted features by using pre-trained machine learning model. In an embodiment, the assistance system 200 may implement classification algorithms to segregate relevant features from the artifacts. In an embodiment, the plurality of features may be further used to train the machine learning model for future extraction process. The plurality of features enables the assistance system 200 to determine intent and actions of the expert while interacting with the virtual simulation associated with performing of task. In addition to above, the extraction of plurality of features minimizes the complexity of the implementation of neural stimulation techniques by reducing the cost of information processing, and to avoid the potential need to compress the information.

Based on the plurality of features, the data collections and analysis module 209 generate execution commands for the user to perform the task. The executed commands, which are to be performed by the user, includes one or more actions and the intent determined from the plurality of features extracted from the one or more brain signals associated with the expert. This can be achieved by neural stimulation techniques known in the art. The neural stimulation techniques may be invasive or non-invasive technologies that are configured to provide motor commands and intent based communication to the user. Most general techniques known in the art are Transcranial Magnetic Stimulation (TMS), Electroconvulsive Therapy (ECT) and the invasive stimulation method are known as Deep Brain Stimulation (DBS). Similar to TMS, Transcranial Electrical Stimulation (TES) is also a non-invasive clinical methodology. Depending on the stimulation techniques, the stimulating devices is positioned on user's head, directly over the desired stimulation area. The stimulation technique provides pulses to user's brain, which in response generate electric current in the nearby neurons to produce motor commands for the user to complete the task. Upon reception of optimal neural stimulation user's body should perform same one or more actions in repeated manner as captured.

In addition to above, the performing of the one or more actions by the user 103 may results in the change of state of the objects while the user is interacting with it for completing the task. The assistance system 200 is further configured to monitor the change in the state of the one or more objects associated with the task while the user 103 is performing the one or more actions associated with the task. The recording module 207 of the assistance system 200 captured the changed state of the one or more objects associated with the task and transmit the updated holographic information of the one or more objects to the skilled expert 104. Upon transmitting the updated holographic information of the one or more objects in real-time, the assistance system 200 may further obtain subsequent brain signals associated with the skilled expert 104 for changed state of the physical objects in order to complete the task. Accordingly, the assistance system 200 is configured to provide remote assistance to the user 103 in real-time for completing the task.

It should be noted that the assistance system 200 may be implemented in programmable hardware devices such as programmable gate arrays, programmable array logic, programmable logic devices, and so forth. Alternatively, the assistance system 200 may be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, include one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, function, or other construct. Nevertheless, the executables of an identified module need not be physically located together but may include disparate instructions stored in different locations which, when joined logically together, include the module and achieve the stated purpose of the module. Indeed, a module of executable code could be a single instruction, or many instructions, and may even be distributed over several different code segments, among different applications, and across several memory devices.

The mixed reality environment for the expert is created including virtual hammer and a virtual object 306 for which the user 303 has requested for assistance. Upon receiving the request from the user and virtual simulation of user's environment, the expert 304 perform one or more actions on the virtual objects 306. The one or more actions performed by the expert 304 are captured in the form of response, gestures, movements or feedback by the expert to the mixed reality environment. The haptic feedback sensor in the mixed reality environment 302 is configured to record the one or more actions of the expert, for which a brain-computer interface 118 obtain the one or more brain signals of the expert 304. The one or more brain signals of the expert 304 indicate an intent and one or more actions of the expert while interacting with the virtual simulation to complete the task. The one or more signals captured form the expert 304 are provided to the assistance system 101 through secured high throughput network 105. The computer-brain interface 110 at the user end is configured to receive secured brain signals. The received brain signals are converted in execution commands for the user 303 and implemented using neural stimulation on the user. The one or more brain signals associated with the expert 304 are processed to extract a plurality of features containing meaningful information for performing the task. The execution commands generated for the user 303 enable the unskilled user to perform one or more actions on the physical objects 305. The assistance system 101 continuously monitor the physical object and detect any change in the state of the physical object when the user is performing the one or more actions on the physical object. Upon detecting a change in the state of physical object, the recording module 108 capture the holographic information of the physical object. The assistance system 101 transmit an updated holographic information of the physical object and received one or more subsequent brain signals from the expert for providing continuous assistance to the user in real time.

Referring now to FIG. 4, a flow diagram illustrating a process overview of providing real-time remote assistance to a user is depicted, in accordance with some embodiments of the present disclosure. A user inputs a query to request for assistance to complete a task into the user interface of the assistance system. As illustrated in the flowchart, a control logic 400, upon receiving user's request, may include the step of capturing holographic information of one or more objects associated with the task to be performed by the user, at step 401. The control logic 400 may further include the step of transmitting the holographic information to an expert identified by the assistance system based on one or more skills required to perform the task, at step 402. The control logic 400 may further include the step of receiving one or more brain signals associated with the expert interacting with a virtual simulation of the one or more objects to perform the task, at step 403. The control logic 400 may further include the step of providing real-time remote assistance to the user by generating execution commands for the user in real-time based on a plurality of features associated with performing the task extracted from the one or more brain signals received from the expert, at step 404.

In some embodiments, the control logic 400 may include one or more of following additional steps: generating neural stimulation for the user based on the execution commands, wherein the execution commands comprises one or more actions and intent determined from the plurality of features extracted from one or more brain signals associated with the expert using a trained machine learning model, at step 404. In some other embodiments, the control logic 400 may include one or more of following additional steps: detecting a change in the state of the one or more objects when the user is performing one or more actions towards completion of the task, and transmitting updated holographic information of the one or more objects to the expert.

At step 401, the assistance system 101 receives a request from the user 103 through user interface 106 requesting for remote assistance to complete a task. The assistance system 101 verifies whether the user is a registered user, else the assistance system 101 allows a new user to register itself. Upon verifying user details, the assistance system 101 captures details of one or more objects for which the user requires remote assistance. The assistance system 101 includes one or more cameras to capture holographic information of the one or more objects associated with the task. The assistance system 101 retrieves a list of experts based on the skills required to complete the task and availability of the expert from the list. In an embodiment, the assistance system 101 may connect with an expert allocator module 111 to allocate a skilled expert for the task.

At step 402, upon identifying the skilled expert, the assistance system 101 transmits the captured holographic information to the expert identified based on one or more skills required to perform the task. The assistance system 101 uses a secured network 105 to share the holographic information and user's request to the skilled expert 104. At expert's end, a mixed reality system 102 is configured to create a virtual simulation of the one or more objects associated with the task. The mixed reality system 102 includes an adaptation module 114 which validates the holographic information received for the user for its correctness and completeness. Thereafter, the adaptation module 114 fetches one or more assets required for generate virtual representation of the one or more objects associated with the task. Further, the adaptation module 114 validates on different states and positions of the one or more objects for creating virtual simulation. Upon fetching, the adaptation module 114 provides the one or more assets to a data visualization module 115 for creating a virtual simulation of the user environment for the skilled expert 104.

At step 403, the mixed reality system 102 receives one or more brain signals associated with the skilled expert 104 while interacting with a virtual simulation of the one or more objects to perform the task. The mixed reality system 102 includes a controller interface 116 which allows user to use gestures, responses and movement in the mixed reality environment. Further, the skilled expert while interacting with the virtual simulation generates touch and vibrations through gestures, responses and movement in mixed reality environment. These touches and vibrations are sensed by the haptic feedback module 117 which provide haptic feedback to the skilled expert to create similar sensory as an individual feels in real world environment. Upon receiving haptic feedback in mixed reality world, the skilled expert 104 generates one or more brain signals which are recorded by a brain-computer interface 118 using any method such as invasive, semi-invasive or non-invasive method. The brain-computer interface 118 records one or more brain signals from the skilled expert 104 while performing one or more actions associated with completing the task. The brain-computer interface 118 records EEG signals associated with the skilled expert 118, which indicate the intent and the one or more actions required to complete the task. The mixed reality system 102 transmits the recorded brain signals to the assistance system 101 to provide real-time remote assistance to the user 103.

In an embodiment, the mixed reality system 102 may encrypt the one or more brain signals associated with the skilled expert 104 using shared security key before transmitting the same over the communication network 105. The assistance system 101 employs secured throughput network to share and receive confidential and sensitive information associated with the user's environment and the EEG signals associated with the skilled expert for security reasons. The security key maybe shared by the assistance system 101 when it triggers the mixed reality system 102 of the skilled expert 104. At user's end, the assistance system 101 uses valid security key to decrypt the one or more brain signals received from the skilled expert 104.

At step 404, the assistance system 101 receives the one or more brain signals via the computer-brain interface 110, and send it to a data collection and analysis module 109 for further processing. The data collections and analysis module 109 extract a plurality of features from the one or more brain signals received from the expert. The plurality of features are extracted to derive meaningful information associated with performing the task from the received one or more brain signals. As explained above in FIG. 2A, the plurality of features are extracted using extraction techniques known in the art. The extracted features are classified to remove artifacts and noise by using a pre-defined machine-learning model. The pre-trained machine learning model may include implementation techniques such as linear analysis, nonlinear analysis, adaptive algorithms, clustering and fuzzy techniques, and neural networks.

The plurality of features after extraction and classification are translated into execution commands for the user. The computer-brain interface 110 allows the assistance system to read information from user's brain and to deliver execution commands to user's brain to perform one or more actions on the physical object. These execution commands are implemented using neural stimulation on the user to enables the user's brain to perform desirable actions for completing the task.

In an embodiment, the one or more actions taken by the user on the one or more objects caused by the neural stimulation may results in change in state of the one or more objects. The recording module 108 records the changed state of the one or more objects and provide the same to the skilled expert 104 to receive subsequent assistance for updated state of the physical till the completion of the task. In an embodiment, the adaptation module 114 triggers the assistance system 101 for last actions after observing the final state of physical object mapped into mixed reality environment. The skilled expert may give final approval of completion of task after observing rendered virtual object in mixed reality world.
